BLE DTM with Zephyr project SDK 2.7.0

RE: BLE DTM with Zephyr project SDK 2.7.0

Hi Vidar, yes I got it running once. I tried again with the same failure, that it does not build any more. Sometimes I can build it, but after flashing the serial communication does not work. Sometimes it does. No idea whats going on. Thats why I do not continue with this topic at the moment. But I will have to implement it into out device for BLE certification. So may be I will contact Nordic again when I pick up this topic. For now we can close this issue.

Thank you very much for your support
Georg

Sorry to hear that. I thought it was working after your previous comment.

I gave up with DTM

I could just get the serial communication running. But I do not know what I have done to get it running.

Hi Vidar,

think I found the reason. May be I mixed up the sample from 2.9.0 and tried to build it with 2.7.0 after build with 2.9.0 failed.

I deleted everything and setup the DTM sample again by taking care of diffenrent versions of SDK

Now I could build it, but: With the nrf Connect DTM program I can not access it. DTM tries to communicate with COM Port, but there is no response. Tried both COM ports provided by DK.

How can I use this example with the nrf connect DTM tool?

Best regards
Georg

Hi Georg,

Thanks, I just wanted to make sure nothing was changed in the project configuration. It seemed like the linker errors did not match the source code. Unfortunately, I have not managed to reproduce the build issue here.

Does your the cmake output in your build log show that this overlay is found as in my case below?

This overlay selects the communication interface to use with DTM:

It would also be helpful if you could share your build log.

Best regards,

Vidar

Hi Vidar,

the zip I have attached. It is just the nrf sample for DTM.

Please have a look at it

Hi,

I see. Yes, that makes sense. Could you make a zip of the direct_test_mode folder in D:/sw/test54Hello/direct_test_mode and upload it here so I can try to find out why the project fails to build?

Hi Vidar,

Yes, my build configuration matches this.

Switching to 2.9.0 was just due to lack of other ideas. Our project bases on 2.7.0 and we like to stay with that.

But building neither works for 2.7.0 nor 2.9.0.

I see you've switched to SDK v2.9.0. Does your Build configuration match this:

Hi Vidar,

thank you for your quick answer. This sounds resonable.

Took the network core with SDK 2.7.0 and get a compile error due to missing header files

Hello,

If you get an error saying NRF_RADIO_Type is not defined, it usually means you have attempted to build the project for the application core instead of the network core. The application does not have direct access to the RADIO peripheral.

Supported build target:

https://docs.nordicsemi.com/bundle/ncs-2.9.0/page/nrf/samples/bluetooth/direct_test_mode/README.html

Best regards,

Vidar
